| Oorja-HalT 12. Aug 2005 | On the surface it seems simple you just have to understand the decrytption of loader.bin. However the issue involved are complex. How do you trace the code to understand the decryption. The only way out i think is virtual drive . Beside if you change loader.bin it catches and displays the bad boy message you also have to reverse it. All in all a novel attempt for reversing thats commandble.All credit goes to monkey you have delivered what you have promised |
